“…Taken as an example, the quasi-periodic layout is a typical means to enhance nonreciprocity. [13,14] On the other hand, magnetized gyromagnetic photonic crystals (MGPCs), [15][16][17] kinds of PCs with the introduction of magnetized magneto-optical materials, are capable of realizing time-reversal asymmetry and bringing about nonreciprocal properties. With appropriate structures in the MGPCs, the band gap effects will help to promote nonreciprocity.…”

The magnetized gyromagnetic photonic crystals (MGPCs), composed of the indium antimonide (InSb) and Yttrium iron garnet ferrite (YIGF) layers, are proposed, which possess the properties of the nonreciprocal wide-angle bidirectional absorption. The periodical defects in the MGPCs work as filters. The absorption bands (ABs) for the positive and the negative propagation arise from the optical Tamm state and resonance in the cavities respectively, and they prove to share no overlaps in the study frequency range. Given ω 0=2.0138 THz, for the positive propagation, the ABs in the high-frequency range are localized in the interval between 0.66ω 0 and 0.88ω 0. In the angular range, the ABs for the TE and TM waves reach 60° and 51°, separately. For the negative propagation, the ABs in the low-frequency range are localized in the interval between 0.13ω 0 and 0.3ω 0. The ABs extend to 60° for the TE waves and 80.4° for the TM waves. There also exists a narrow frequency band in a lower frequency range. The relevant factors, which include the external temperature, the magnetic fields applied to the YIGF, the refractive index of the impedance matching layer, and the defect thickness, are adjusted to investigate the effects on the ABs. All the numerical simulations are based on the transfer matrix method. This work provides an approach to the design of the isolators and so on.

“…Furthermore, the appropriate breaking of the periodicity and symmetry in the spatial topological arrangement can bring about some interesting peculiarities and the quasi-periodic layout is also a prevalent topic in the research of GMPCs. Mehdi Zamani et al [21] explored the optical and magneto-optical features of quasi-periodic Octonacci GMPCs and found that the transmittance and large Faraday rotation responses for the two polarization modes are angle-insensitive in the configuration of Octonacci arrangement. The transverse magnetooptical Kerr response and corresponding multiple plasmonrelated resonances were probed by Kalish et al [22] in a broad frequency region via the 1D magnetoplasmonic quasicrystal arranged by the Fibonacci sequence.…”

In this paper, an ultra-wide multiband unidirectional absorber based on 1D gyromagnetic magnetized photonic crystals (GMPCs) comprising ferrite material and isotropic dielectrics is investigated under transverse magnetization for transverse electric mode within the infrared regime by the transfer matrix method. Due to the Voigt magneto-optical effect, the magnetically modulated absorber possesses multiple preeminent one-way absorption bands, which run at 12.24–18.80, 25.25–50.05, 51.13–74.90 and 76.67–93.88 THz and in the reverse propagating direction. The absorber displays a splendid reflection phenomenon. These perfect nonreciprocal results can be ascribed to the destruction of the space-time reversal symmetry on account of the anisotropic gyromagnetic ferrite material and quasi-periodic arrangement of the proposed GMPCs. The comparisons of the absorption capacity among the general Fibonacci sequence, the periodic sequence and Thue–Morse sequence are discussed, and the general Fibonacci sequence has its superiority in the expansion of the one-way absorption bandwidth due to its better self-similarity. Besides, the regulative effects of the magnetic field intensity, damping factor and thicknesses of materials on the one-way absorption features are analyzed specifically. This research provides a promising design approach to the tunable infrared optical isolator, waveguide and circulator through the magnetized materials.

Using the transfer matrix method, the present paper attempt to determine the properties of the photonic spectra of the Dodecanacci superconductor-metamaterial one-dimensional quasiperiodic multilayer. The numerical calculation is supported by using the transfer matrix method. At first, we analyze the transmission for Dodecanacci quasicrystal for different generations. After that, we analyze the effect of the thickness of the building blocks and the operating temperature. We observed that a vast number of forbidden bandgaps and transmission pecks are developed in its transmission spectra up to a certain generation number of Dodecanacci quasiperiodic sequence. If the generation number increases further, then the bandgaps become wider. According to the obtained results, depending on its generation, this structure can be used as an optical reflector or narrowband filter.
